49x2 - 81 is an example of the difference of two

Shkiper50 [21]

Answer:

(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

Step-by-step explanation:

Formulas are used to factorize the polynomials.

In the given question, we can see a difference of squares

the difference of squares can be factorized using the formula

$a^2-b^2 = (a+b)(a-b)$

Here a^2 and b^2 are squares and factorized as sum and difference of numbers.

So in the given options,

(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

7. A sphere and a circular cylinder have the same radius, r, and the height of the cylinder is 2r. a. What is the ratio of the v

Nastasia [14]

Answer: (a) 2 : 3

(b) 4 :1

Step-by-step explanation:

$\\$ The Volume of a sphere is given as

$\frac{4}{3}$ $\pi$ $r^{3}$ and the volume of a cylinder is given as $\pi$ $r^{2}$ h

$\\$ The ration of their volume is the same as Volume of Sphere : Volume of Cylinder , which gives

$\\$ $\frac{4}{3}$ $\pi$ $r^{3}$ : $\pi$ $r^{2}$ h

$\\$ recall that they have the same radius and the height of the cylinder is 2r , taking this into consideration, we have

$\\$ $\frac{4}{3}$ $\pi$ $r^{3}$ : $\pi$ $r^{2}$ (2r)

$\\$ which gives 4 : 6 = 2 :3

$\\$ (b) The area of a sphere is 4 $\pi$ $r^{2}$ and the surface area of the circular cylinder is $\pi$ $r^{2}$

$\\$ The ratio then gives

$\\$ 4 $\pi$ $r^{2}$ : $\pi$ $r^{2}$ ,which gives

$\\$ 4 : 1
